Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2
To write this value simply write the first part of the value before the decimal point
Which is 34
Then since it says 12 hundredths, make sure to place them after the decimal place.
0.12 = 12 hundredths
34.12 would be the answer.
For the probability of one thing or another, you add the two probabilities together. In that case, the probability of getting 3 or 4 is (2/3) + (1/8) = 19/24
Answer:
20
Step-by-step explanation:
10 is equal to the side infront of it. 10 +10 = 20
rounding it to the nearest degree will also be 20
